Anti-Environmental Signals and Deforestation: Evidence from Brazil
Chain Reactions: How Businesses Plan to Respond to the EU Deforestation Regulation in Brazil, the Congo Basin, and Europe
The 2023 European Union Regulation on Deforestation‐free Products (EUDR) is a transnational regulation aimed at addressing forest loss along the value chains of forest‐risk commodities. Grounding our analysis in new institutional theory with distinct behavioral drivers explaining actor behavior, and using qualitative methods, we draw on the cases of Brazil, the Congo Basin, and the EU to understand the behavior of forestry and agricultural sector…
Telecoupling of governance systems under the EU deforestation regulation: Scenarios for the Brazilian beef and soy value chains
Commodity imports by the European Union (EU) are an important driver of land use change in agricultural producer countries. The new EU Deforestation Regulation (EUDR) encompasses seven relevant commodities that can only enter the EU market if they are certified deforestation-free. The EUDR may lead to changes in land use governance and value chain governance of major trading partner countries, which can be described as telecoupling at the policy …
Votes for roads: Electoral motives of road infrastructure development in Kenya
Road investments are intended to promote economic development and enhance access to social services. Ideally, such infrastructure projects should be prioritized based on objective assessments of local needs and development potential. However, political considerations often influence public road investment decisions, favoring specific electoral groups. This study analyzes the role of electoral motives in road development in Kenya using a hybrid mo…
Climate-relevant land cover composition and configuration trajectories in Europe
Land use and land cover change (LULCC) can affect the climate system by altering biophysical surface characteristics. At the local scale, climate regulating functions are co-determined by land cover composition and configuration, i.e. the proportions and the spatial arrangement of land cover types. However, research on the relationship between LULCC and climate often focuses individually either on compositional or configurational aspects. As a re…

Explaining compliance with voluntary sustainability standards: A case study from Colombia's coffee belt
This paper aims to explain producer compliance with Voluntary Sustainability Standards ( VSS ), instruments of private governance regarded as key to solving sustainability issues in global value chains. We employ a dataset of 194 Colombian coffee producers who are certified by one or more VSS to break down the factors leading to farmer compliance with environmental criteria linked to VSS . In total, we analyse 19 environmental criteria, derived f…
Incentives for biodiversity conservation under asymmetric land ownership
Cost-effectiveness and income effects of alternative forest conservation policy mixes for the Peruvian Amazon
To reduce deforestation and mitigate climate change, the Peruvian government proposed and partially implemented incentive- and disincentive-based forest conservation policies, especially in the Amazon, where most of the country’s deforestation occurs. However, to date, little is known about the magnitude of the trade-offs between cost-effectiveness and welfare effects of such a policy mix. To explore this question, this paper develops a spatially…

Action needed to make carbon offsets from forest conservation work for climate change mitigation
Carbon offsets from voluntary avoided-deforestation projects are generated on the basis of performance in relation to ex ante deforestation baselines. We examined the effects of 26 such project sites in six countries on three continents using synthetic control methods for causal inference. We found that most projects have not significantly reduced deforestation. For projects that did, reductions were substantially lower than claimed. This reflect…
Public policies and global forest conservation: Empirical evidence from national borders
Protecting the world’s remaining forests is a global policy priority. Even though the value of the world’s remaining forests is global in nature, much of the protection has to come from national policies. Here, we combine global, high resolution remote sensing data on forest outcomes (tree-cover loss, forest degradation, net primary production) and two complementary econometric research designs for causal inference to first quantify how much it m…

Beyond Deforestation Reductions: Public Disclosure, Land-Use Change and Commodity Sourcing
Spatially heterogeneous effects of collective action on environmental dependence in Namibia’s Zambezi region
Many poor rural households depend on products from non-cultivated environments for subsistence and commercialization. Collective action schemes, such as community-based natural resource management (CBNRM), aim at maintaining natural resource quality and thus potentially contribute to the sustainability of environmental income sources. Little is known about whether and under which contextual conditions these schemes effectively promote environment…
Quo vadis global forest governance? A transdisciplinary delphi study
Benefits and costs of incentive-based forest conservation in the Peruvian Amazon
Overstated carbon emission reductions from voluntary Redd+ projects in the Brazilian Amazon
Reducing emissions from deforestation and forest degradation (REDD+) has gained international attention over the past decade, as manifested in both United Nations policy discussions and hundreds of voluntary projects launched to earn carbon-offset credits. There are ongoing discussions about whether and how projects should be integrated into national climate change mitigation efforts under the Paris Agreement. One consideration is whether these p…
The rotten apples of Brazil's agribusiness
Brazil's inability to tackle illegal deforestation puts the future of its agribusiness at risk
Focus on leakage and spillovers: Informing land-use governance in a tele-coupled world
Governing land use to achieve sustainable outcomes is challenging, because land systems manifest complex land use spillovers—i.e. processes by which land use changes or direct interventions in land use (e.g. policy, program, new technologies) in one place have impacts on land use in another place. The ERL issue ‘Focus on Leakage: informing Land-Use Governance in a Tele-coupled World’ builds on discussions in an international expert workshop condu…
Evaluating Redd+ at subnational level: Amazon fund impacts in Alta Floresta, Brazil
Bioeconomy futures: Expectation patterns of scientists and practitioners on the sustainability of bio‐based transformation
Economic sectors relying on the use of biological organisms, processes, and principles to create products and services are expected to experience accelerated growth due to innovation in the bioeconomy. Associated benefits and risks for sustainable development are increasingly subject to societal debate. We compiled expectation patterns from a global survey with bioeconomy experts and a systematic literature review identifying areas of consensus a…
Spatially-explicit footprints of agricultural commodities: Mapping carbon emissions embodied in Brazil's soy exports
Reliable estimates of carbon and other environmental footprints of agricultural commodities require capturing a large diversity of conditions along global supply chains. Life Cycle Assessment (LCA) faces limitations when it comes to addressing spatial and temporal variability in production, transportation and manufacturing systems. We present a bottom-up approach for quantifying the greenhouse gas (GHG) emissions embedded in the production and tr…
Tourism opportunities drive woodland and wildlife conservation outcomes of community-based conservation in Namibia's Zambezi region
Initiatives to promote community-based natural resource management (CBNRM) have been evaluated with mixed results in socio-economic and ecological outcome dimensions. In Namibia, community conservancies are being established since the 1990s mainly to reconcile wildlife conservation and rural development. As Namibia gears up for participation in Reducing Emissions from Deforestation and Forest Degradation (REDD+), land use and land cover change an…
Environmental Income and Rural Livelihoods: A Global-Comparative Analysis
This paper presents results from a comparative analysis of environmental income from approximately 8000 households in 24 developing countries collected by research partners in CIFOR's Poverty Environment Network (PEN). Environmental income accounts for 28% of total household income, 77% of which comes from natural forests. Environmental income shares are higher for low-income households, but differences across income quintiles are less pronounced…
Effectiveness and synergies of policy instruments for land use governance in tropical regions
Safety Nets, Gap Filling and Forests: A Global-Comparative Perspective
In the forest–livelihoods literature, forests are widely perceived to provide both common safety nets to shocks and resources for seasonal gap-filling. We use a large global-comparative dataset to test these responses. We find households rank forest-extraction responses to shocks lower than most common alternatives. For seasonal gap-filling, forest extraction also has limited importance. The minority of households using forests for coping is asse…
Linking Forest Tenure Reform, Environmental Compliance, and Incentives: Lessons from Redd+ Initiatives in the Brazilian Amazon
Recent transformations of land-use and land-cover dynamics across different deforestation frontiers in the Brazilian Amazon
After forest governance reforms by the Brazilian government, Amazon deforestation rates dropped by almost 80% between 2004 and 2012. Since then, however, deforestation has slowly increased again, casting doubts on the long-term sustainability of past conservation policy achievements. Clearly, deforestation rates and the associated local drivers of land-use and land-cover change differ considerably across the region, and adapting public policies t…
Forest law enforcement in the Brazilian Amazon: Costs and income effects
Exploring criteria for transformative policy capacity in the context of South Africa’s biodiversity economy
In the wake of increasingly complex sustainability challenges, societal transformations of currently unsustainable socio-economic production and consumption patterns are imperative. At the same time, international scholarly debates emphasise a decline in the policy capacity of societal actors to deal with the complexity of putting policy into practice. South Africa’s national development strategy of utilising its unique biodiversity for developin…
Smallholder Specialization Strategies along the Forest Transition Curve in Southwestern Amazonia
Rural specialization strategies can be examined within the forest transition framework. We compared smallholder livelihood strategies between neighboring southwestern Amazonian sites at different stages along the forest transition curve. Surveys of 243 households in Pando, Bolivia and Acre, Brazil, within and outside of two major protected areas, confirmed a higher reliance on forest-based income in forest-rich Pando than in Acre. In Acre, forest…

Mainstreaming Impact Evaluation in Nature Conservation: Mainstreaming impact evaluation
An important part of conservation practice is the empirical evaluation of program and policy impacts. Understanding why conservation programs succeed or fail is essential for designing cost-effective initiatives and for improving the livelihoods of natural resource users. The evidence we seek can be generated with modern impact evaluation designs. Such designs measure causal effects of specific interventions by comparing outcomes with the interve…
The implementation costs of forest conservation policies in Brazil
Governance of the Bioeconomy: A Global Comparative Study of National Bioeconomy Strategies
More than forty states worldwide currently pursue explicit political strategies to expand and promote their bioeconomies. This paper assesses these strategies in the context of the global Sustainable Development Goals (SDGs). Our theoretical framework differentiates between four pathways of bioeconomic developments. The extent to which bioeconomic developments along these pathways lead to increased sustainability depends on the creation of effect…
Land use mediated GHG emissions and spillovers from increased consumption of bioplastics
Bioplastic production is a small but fast growing sector in the global bioeconomy, which may benefit from public support measures in the future as governments seek to promote more sustainable consumption patterns. Here we assess the potential net economy-wide impacts of a 5% bioplastic target relative to current plastic consumption in the main producing regions. We compare two alternative policy strategies to achieve the target in a general equil…

Selection biases and spillovers from collective conservation incentives in the Peruvian Amazon
Payments for ecosystem services are becoming popular components in strategies to conserve ecosystems and biodiversity, but their effectiveness remains poorly documented. Here we present counterfactual-based evidence on the conservation outcomes of the pilot stage of Peru's National Forest Conservation Program (NFCP). The NFCP provides direct payments to indigenous communities in the Amazon, conditional on avoided deforestation and the adoption of…
Land speculation and conservation policy leakage in Brazil
The Brazilian Amazon and Cerrado biomes have been subject to strong pressure from agricultural expansion over the past decades. It is frequently claimed that the associated tree cover loss was partly driven by land speculation. In the mid-2000s, the Brazilian government implemented an innovative policy regime to combat deforestation with a strong focus on the Amazon region. While there is solid evidence that the new environmental governance appro…
Quantifying the global cropland footprint of the European Union’s non-food bioeconomy
A rapidly growing share of global agricultural areas is devoted to the production of biomass for non-food purposes. The expanding non-food bioeconomy can have far-reaching social and ecological implications; yet, the non-food sector has attained little attention in land footprint studies. This paper provides the first assessment of the global cropland footprint of non-food products of the European Union (EU), a globally important region regarding…
